<h3 id="rationale">Rationale:</h3>
<p>Shells have two sets of comparison operators: for integers
(<code>-eq</code>, <code>-gt</code>, ...) and strings (<code>=</code>,
<code>&gt;</code>, ...). ShellCheck has noticed that you're using an
integer comparison with string data.</p>
<p>If you are in fact comparing integers, double check your parameters.
Certain mistakes like <code>$$foo</code> or <code>${bar}}</code> can
introduce non-numeric characters into otherwise numeric arguments.</p>
